Will I Be Able to Use This?

I'm looking at a copy of a book that is "iPad compatible." It says that it is PDF. I do not own an iPad, but I do have a MacBook Pro. I am looking to buy the book to cut and paste some passages into a study summary for an exam (yes, this is legal and within fair use!) If I buy this iPad Book, will I be able to copy and paste from it? I don't want to spend $60 and find out that I cannot.

Thanks for the reply, bobtomay. I know very little about iPads... Would it be possible to download the app onto my MacBook Pro? Also, if I borrowed an iPad (a friend has one), could I then render the book into PDF? I really just want it for copy-paste purposes.
